TITLE: FMVSR INTERPRETATION

TEXT: This is in reply to your letter to Mr. Hartman concerning the tire identification and record keeping regulation (49 CFR Part 574) requesting that you be allowed to code by pressure chamber rather than by matrix.

Since the pressure chamber is used by Bandag to serve a purpose similar to the purpose served by the matrix in hot processing of retreaded tires, you may assign(Illegible Word) numbers to your pressure chambers and use this code number in place of the matrix code number required by Part 574.
